Introduce:Annealing is a heat treatment equipment in the machinery industry, its purpose is to make the casting, forging, welding or cutting the workpiece material or softening, reduce the hardness to improve the plasticity and toughness, make the chemical composition homogenization, removal of residual stress, or physical performance expectations.

Introduce:The constant pressure drying process is to make constant pressure on the axis of the coil during the drying process, so that the insulation parts in the coil can be fully compressed during the whole drying process, thereby improving the short-circuit performance and service life of the transformer. In order to apply the hydraulic system with constant pressure, the cylinder is applied to the axial pressure of the coil. The hydraulic system can not only keep the constant pressure, but also adjust the pressure according to the needs. This equipment is mainly used for the suppression of the 110KV and above transformer coils, and the pressure is constant. It is the most ideal device for handling the coil.

Introduce:The device is a vacuum pressure impregnating equipment. It is mainly applied to coil impregnation treatment of power transformers, vacuum pressure impregnation is a widely applied technology in transformer industry, and has been widely applied at home and abroad.
The vacuum pressure impregnation process for transformer can solve many problems in the process of transformer production and application, improve the insulation performance of transformer, improve the strength of transformer coil, and reduce the pollution of ordinary dipping paint to the environment.

Introduce:Kerosene vapor phase drying equipment is currently used in transformer industry transformer or coil drying of an advanced special equipment. It is compared with the traditional drying technology and equipment, this equipment has the characteristics of complicated structure and process parameters. The built-in desiccant vapor drying equipment and external desiccant vapor drying equipment compared. More safety, desiccant steam utilization is high, the structure is relatively simple. The use of 31500KVA/100 and above applies to products.
